Definitions

  • This invention relates to a decoating device, for precoated printing plates developed with liquid toner, having pairs of conveyor and squeezing rollers between which the printing plates pass, and having a spray device for spraying decoating liquid onto the developed surface of the individual printing plates.
  • Printing plate processing units of compact construction as manufactured by KALLE Niedermik der Hoechst AG, are known, by which printing plates are decoated or developed, rinsed, fixed/gummed and dried in one pass.
  • the decoating agents and the rinsing water are kept in constant circulation by circulating pump units. Because of the closed circuits for the decoating liquid and the rinsing water, permanent connections to a water pipe and drain are unnecessary, so that the known decoating apparatus can be set up at any site.
  • Other types of known printing plate processing units develop, rinse, fix/gum and dry the printing plates in one pass.
  • These devices are, for example, fitted with an automatic topping-up system for the developer concentrate to stabilize the developer which circulates in a closed circuit inside the apparatus.
  • the developer is cooled by a continuous water cooling system which is thermostatically monitored.
  • the developer temperature is regulated by means of a thermostatically monitored developer heating system.
  • the processing of plates on the printing plate processing units is matched to the particular requirements by an independent speed adjustment for the plate pass and for the scrubbing elements such as, for example, brush rollers or plush-covered rollers.
  • a decoating device for precoated printing plates developed with liquid toner comprising pairs of conveying and squeezing rollers between which the printing plates pass through and a spray device in a spraying section for spraying decoating liquid onto the developed surface of the individual printing plates
  • the spray device comprises a plurality of containers, filled with different decoating liquids, with the decoating liquids being under pressure, at least one flat jet nozzle in a spraying section, the nozzle or nozzles being connected to the containers of decoating liquids via at least one valve, wherein a first sensor controls the opening times of the valves in accordance with the format of the printing plate passing through the decoating device, and wherein the spraying section is followed by a heating zone in which the decoating liquid film on the printing plate is heated to facilitate the decoating action.
  • FIG. 1 is a schematic sectional representation of a first embodiment of a decoating device according to the invention
  • FIG. 2 is a schematic representation of an embodiment of the decoating device slightly modified with respect to FIG. 1;
  • FIG. 3 is a schematic sectional view of a further embodiment of the decoating device according to the invention.
  • a decoating device wherein several containers are filled with diferent decoating liquids under pressure and each container is connected to at least one flat-jet nozzle in a spraying section via a valve, preferably a multiway valve, wherein a first sensor controls the opening times of the valve or valves in accordance with the format of the printing plate passing through and wherein the spraying section is followed by a heating zone in which the decoating liquid film is heated with the printing plate.
  • a trough for collecting the decoating liquid sprayed laterally across the printing plate, and for conveying this liquid to a collecting container connected to the trough.
  • the multiway valve is connected to a water connection which supplies water via the multiway valve to the flat-jet nozzle for rinsing the jet orifices.
  • the invention achieves the advantages that a printing plate developed with liquid toner such as, for example, an Elfasol® printing plate maintains the original quality of the toner image even after the decoating, and the results are reproducible with great precision and appropriate quality since each printing plate is treated with a defined quantity of fresh decoating liquid in each case. Since the decoating liquid is sprayed as a thin film of uniform thickness onto the surface of the printing plate, it can be brought to elevated temperature within a short time, as a result of which the decoating rate, as described above, is increased. It is consequently not necessary, as in the case of known decoating devices, to bring the entire stock of decoating solution to the elevated temperature, which obviously takes longer.
  • liquid toner such as, for example, an Elfasol® printing plate
  • an action zone of, for example, 50 cm for the elevated temperature of the decoating liquid and rates of advance of up to 3 m/min are possible.
  • positive plates and electrophotographic printing plates such as, for example, Elfasol® printing plates, require the decoating liquid to act for less time than negative plates.
  • Liquid toned electrophotographic printing plates in general exhibit a higher resolution than plates developed with dry toner.
  • the toner image or the toner mask on the surface of the printing plate is resistant to aqueous alkaline solutions which form the basis of the decoating liquids.
  • Toner layers can in general readily be decoated, but, depending on the degree of use of the decoating liquid, the danger exists of overdecoating or underdecoating of the toner image, in which case the image quality is not maintained.
  • Qualitatively satisfactory decoating is only possible in a narrow range of process parameters.
  • a certain overdecoating is in general desirable in order to compensate in advance for the dot increase in the case of a high print run of the printing plate, but underdecoating should be avoided if possible.
  • decoating with a defined quantity of decoating liquid in the form of a thin film and the one-time use of the decoating solution should be aimed at.
  • FIG. 1 A diagrammatic representation of the construction of a decoating device 21 is shown in FIG. 1.
  • a printing plate 1 which is to be decoated is slid over a loading table 2 into the roller gap of a conveyor roller pair 3.
  • the front edge of the printing plate 1 actuates a first sensor 4 which is provided at the rear edge of the loading table 2.
  • a first sensor 4 As soon as the first sensor 4 registers the front edge of the incoming printing plate 1, it delivers a signal to a multiway valve 5, for example, a magnetic multiway valve, which is switched on with a certain time delay.
  • a multiway valve 5 Connected to the multiway valve 5 are several containers 5a, 5b, 5c which are filled with various decoating liquids for various types of printing plate 1.
  • the decoating liquid in the individual containers 5a, 5b, 5c is under a pressure between 1 to 3 bar.
  • the output side of the multiway valve 5 is connected to at least one flat-jet nozzle 6 which is situated in a spraying section 22.
  • the opening and closing times of the multiway valve 5 are controlled in accordance with the format of the printing plate 1 which is passing through, i.e., in accordance with the particular length of the printing plate 1 in the pass direction.
  • the flat-jet nozzle 6 sprays, within the spraying section 22, the surface of the printing plate 1 which is passing through.
  • Two to six flat-jet nozzles 6 may extend transversely to the pass direction of the printing plate 1 across the width of the printing plate.
  • the number of flat-jet nozzles 6 depends on the processing width of the printing plate 1.
  • the supply of the decoating liquid or solution to the flat-jet nozzle 6 is controlled by the multiway valve 5, filters (not shown) being connected between the containers 5a to 5c and the multiway valve 5 or between the latter and the flat-jet nozzle or nozzles 6 to filter out impurities in the decoating solution.
  • the latter switches off the multiway valve 5 with a time delay.
  • the multiway valve 5 is connected to a water connection 20 which, after the supply of decoating solution to the multiway valve 5 has been switched off, delivers water via the multiway valve 5 to the flat-jet nozzle 6 in order to rinse the nozzle orifices of the latter and consequently prevent them from clogging.
  • the spraying section 22 is followed by a heating zone 9 in which the printing plate 1 and the film of decoating liquid or solution situated thereon are heated to a preselected temperature in the range from about 25° to 55° C.
  • a preselected temperature in the range from about 25° to 55° C.
  • five to twelve radiators with reflectors may be present to achieve the desired temperature.
  • the number of radiators depends on the length of the desired heating zone, i.e., on the length of the action zone of the heated decoating liquid on the surface of the printing plate 1.
  • FIG. 1 three radiators 25 are shown.
  • the temperature is regulated by means of a thermocouple (not shown) discretionally situated between the radiators 25 and the printing plate 1. In general it takes about 10 minutes for the radiators 25 of the heating zone 9 to heat up sufficiently to assume a stable operating state. The power consumption is then, for example, about 1.2 kW.
  • rollers 10 for example spiked rollers, which bring about the continued conveying of the printing plate 1 without them having to be gripped from above.
  • a pair of squeezing rollers 11 which clean from the surface of the printing plate 1 detached layers and floating decoating liquid.
  • the distance between the pair of transport rollers 3 and the pair of squeezing rollers 11 is, for example, on the order of about 660 mm.
  • the action zone of the heated decoating solution within the heating zone 9 is then about 500 mm.
  • the spiked rollers 10 in the heating zone 9 take over the conveying of the printing plates 1, which are shorter than 660 mm, as soon as they have passed the pair 3 of conveying rollers.
  • the spiked rollers 10 may produce scratches on the back of the printing plate 1. If these are not desired, the distance between the pair 3 of conveying rollers and the pair of squeezing rollers 11 must be shortened to about 410 mm so that even the shortest printing plate used in newspaper printing can be forcibly conveyed by the two pairs of rollers.
  • the pair of squeezing rollers 11 is followed by a second sensor 14 which, on registering the front edge of a printing plate 1 which is passing through, sets in operation a cleaning station 23 and a gumming station 24 which are connected downstream of the heating zone 9.
  • the cleaning station 23 comprises a fresh-water rinsing system 15, a cleaning brush 16 and a pair of squeezing rollers 17 for cleaning, neutralizing and squeezing the cleaning water sprayed on from the printing plate surface.
  • a drainpipe 26 is connected to the cleaning station 23.
  • a spraying nozzle 18 which sprays the gumming solution onto the printing plate surface. This is followed by a pair of rollers 19 which squeezes the excess gumming solution from the printing plate surface for collection in a container 27.
  • the rear edge of the printing plate 1 switches off the decoating device 21 by means of the second sensor 14 with a time delay so that the printing plate 1 can be unloaded onto an unloading table 28.
  • the flat-jet nozzles 6 are, as mentioned previously, rinsed with water via the water connection 20 and the multiway valve 5 in order to prevent clogging of the orifices of said flat-jet nozzles 6.
  • the flat-jet nozzles 6 are spray nozzles which have a predetermined spraying angle of, for example, 90° and a spraying width predetermined thereby. Said nozzles deliver a flat-jet spread out in a fan shape.
  • the spraying pressure of said flat-jet nozzles may be varied so that the quanity of decoating liquid sprayed on can be selected in accordance with the requirements for optimum decoating with a given printing plate pass speed and a fixed action zone within the heating zone.
  • the container need be selected in each case from the containers 5a, 5b, 5c and connected to the multiway valve 5 which contains the decoating liquid matched to the type of printing plate.
  • FIG. 2 shows an embodiment of the decoating device 21 which is slightly modified compared with FIG. 1.
  • this embodiment is more compactly constructed and essentially contains the same components as FIG. 1, with the exception that no spiked rollers 10 are present in the heating zone 9.
  • the printing plate 1 to be decoated is slid into the pair of conveying rollers 3 across the loading table 2.
  • the decoating device 21 is switched on at the instant at which the first sensor 4 detects the front edge of the printing plate 1.
  • the decoating solution or liquid is supplied via the multiway valve 5 and via a filter (not shown) to the flat-jet nozzle or nozzles 6 in the spraying section 22.
  • the flat-jet nozzles 6 are switched on during the complete pass of the plate.
  • the heating zone 9 in which a heating system 29 provides for the selected temperature.
  • the developer layer largely detached, is squeezed off the surface of the printing plate 1 along with the residual decoating solution by the pair of squeezing rollers 11.
  • the liquid is collected in the collecting trough 12 and conveyed to the container 13 situated beneath it.
  • the subsequent washing of the printing plate surface by the fresh-water sprayed on by the fresh-water rinsing system 15 and the brushing of the printing plate surface by the cleaning brushes 16 cleans the printing plate 1 of layer residues which are squeezed off by the pair 17 of squeezing rollers and flow into the drainpipe 26.
  • the gumming solution is applied via the spraying nozzle 18 and excess of it is squeezed off by the roller pair 19.
  • the completely decoated printing plate 1 is unloaded onto the unloading table 28.
  • a single sensor 4 is provided which is disposed in front of the first pair 3 of conveyor rollers. Since the printing plates 1 pass through the decoating device 21 with a predetermined pass speed, it is sufficient if a single sensor 4 registers the front and rear edge of each printing plate 1 and sequentially sets the various stations of the decoating device 21 in operation with a suitable time delay with respect to the particular registering instant of the front and back edge and also switches them off again. According to the type of printing plate to be decoated, the particular container of the decoating liquid suitable for the type of plate is selected before the printing plate 1 is loaded.
  • One-way valves 36a, 36b, and 36c are situated in each case in the pipes from the individual containers 5a, 5b and 5c to the flat-jet nozzle or nozzles 6. After registering the front edge of an incoming printing plate 1 the sensor 4 opens, after a suitable time delay, the one-way valve in the pipe from the selected container in order to admit decoating liquid to the flat-jet nozzles 6.
  • the overpressure in the containers 5a to 5c is, as in the case of the other embodiments, 1 to 3 bar.
  • a single multiway valve is used in this embodiment instead of the three one-way valves.
  • the embodiment in FIG. 3 has a heating section which is split-up and which comprises a preheating zone 30 in front of the spraying section 22 and a main heating zone 32 after the spraying section 22.
  • the preheating zone 30 the printing plate 1 is heated to a temperature between about 20° and 30° C., and in the main heating zone 32, it is subsequently heated to a temperature of up to about 55° C.
  • twin radiators 31 which heat up the printing plate 1 more rapidly and more uniformly than single radiators.
  • a further pair of conveying rollers 33 which is provided between the preheating zone 30 and the spraying section 20, together with the pair of squeezing rollers 11 at the end of the main heating zone 32, ensure a reliable forcible propulsion of the printing plate 1 which is passing through.
  • a cleaning trough 34 which is filled with a cleaning liquid, for example water, and which can be moved within the spraying region 22.
  • a cleaning liquid for example water
  • the cleaning trough 34 is connected to a hydraulic jack 35 which raises or lowers the cleaning trough 34 along an inclined line.
  • the cleaning trough 34 is moved by the hydraulic jack 34 from a position outside the flat-jet of the one or more flat-jet nozzles 6 to a position in which the nozzle orifice of the flat-jet nozzles 6 is immersed in the cleaning liquid in the cleaning trough 34.
  • This cleaning process is carried out every time before switching over from one of the containers 5a to 5c to another of said containers and also before the decoating device 21 is switched off in order to counteract the clogging of the orifices of the flat-jet nozzles 6 by the rinsing.
  • lhe cleaning station 23 and the gumming station 24 of this embodiment are identical to the corresponding stations in the embodiments in FIGS. 1 and 2 and are therefore not described further.
